This paper presents the results of the investigation of the thermodynamic properties of I-aluminum oxynitride (AION). The phase relations and thermodynamic properties of NON were analyzed and the Gibbs energies of NON with different compositions and temperatures were calculated by a thermodynamic quasi-parabola rule. Potential phase diagrams of Al-O-N system at different conditions have also been calculated. The synthesis conditions of NON have been determined. NON was synthesized by sintering the starting materials at 25MPa in N-2 flow at 2073K for 3h. Crystal characteristics and microstructures of AION were determined.
